I notice there are 2 different types of repair kits available for the Intake Manifold. I have the P2006 code (stuck closed intake runner flap for bank 1). Which repair kit should I purchase? These are the 2 options.

The difference between these two options being that #1 simply comes with the lever and connecting rods, and #2 comes with the lever and actuator (no rods). If #2 is the correct repair kit, I will also be purchasing a set of gaskets to go with it. Thank you for your help!

I have the same problem all of the machanical parts are not broken. gonna runs a separate valcuum line to the actuator to see if it’s working.

I would check the solenoids if that’s the case.

Seems like the actuators are not getting triggered, could it be a vacuum leak? A solenoid? A change over valve? I’m stuck here and can’t figure out what it is. When the car is at 4000 RPMs I look in the front of the manifold and the actuators dont move. Please help.

Everything was fine and the code disappeared. Later that day I got a P2004 code, I removed the manifold and inspected, everything was fine and working, no broken parts and the inside flaps moved freely without resistance. This code P2004 persists. Could it be the Solenoid? And how can that be diagnosed? When I have have someone in the car revving it at different Rpms I don’t see any movement on the intake actuators. Could it be a vacuum issue? I’m scratching my head on this one.
